Specication of Letters Patent.

Patented May 20, 1913.

.ppucafionmed November 20, 1912. SeraLNo. 732,542.

To all whom it may concern v Be it known that I, GEORGE SMITH, a citizen of the United States residing at Philadelphia, in the county ofI hiladelphia and State -of Pennsylvania, have invented new and useful Improvements in .Locks, of which the following is a specification.'

This invent-ion relates to locks and more particularly to permutation locks.

One of the principal objects of the invention is to provide asimple and eflicient structure of this character whereby the combination may be rapidly set up and thetumblers locked in set position.

Another object of the invention is the provision of a lock of this character so constructed and arranged within the door that the tumblers may be set directly from either side of the door.

Still-another object of the invention is the provision of a lock of this character wherein thetumblers or bolt locking disks are ei:- posed through opposite sides of the door 1n such positionthat `they may be manipulated directly, provision being made for cha ng the combination without removing the ock from the door or disassembling its parts.

Further objects of this invention -willappear as lthe following specific description is read .in vconnection with the accompanying drawings `which form Aa part of this application, and in which Fi ure l is a vertical sectional view through the ook shown applied to -a door. Fig. ;2 is a detail elevation of the door showin the lock-applied thereto. Fig. 3 is a vertica sectional view on the line 3 3 of Fig. 1. Fig. 4 is a view similar to 1 `with 4the disks arran d so as to 'permit the bolt to slide in eit er direction. Fig. 5 is a Vertical sectional view on the Iline 5-.5 of Fig. 4 ona somewhat reduced scale. Fig. 6 is a section on the line 6 6 of Fig. 4. Fig. 7 is an enlarged detail side elevation. Fig. '8 is a rspective View of one of the 'tumblers. Fi 9 is a perspective view ofthe locking bo t.y Fig. 10 is a perspective view of the tumbler lock.

Referring more particularly to the drawings, 1 represents an ordinary door and 2 the door frame provided, in this instance, with a keeper plate 3 having a socket 4 to receive a sliding. locking bolt 5 as will be hereinafter described. This locking bolt is slidably mounted in a channel 6 formed in the door and in a casing 7 secured within the recess or aperture 8 also formed in the doorvand extending upon opposite sides'of the channel '6. The bolt is guided in its movements :by the casing 7 and by the guiding and face plates 9 .and 10, the yformer-having va slot ll communicating with the a rture therein Afor the purpose of permitting the locking keys 12 to pass through the same. The lockingl keys are all formed integrally with the bolt as shown in Figs. 1 and 4 and are alined upon the under side thereof, being arran ed .in spaced relation so as to permit the ree rotation of the webs 13 of the tumblers 14 to pass therebetween when the bolt is in Aprojected or retracted position. Each tumbler is-constructed of a web 13 centrally apertured as shown at 15 and an annular integral ring 16 having a plurality of proj 18 in the base of which is formed sockets 19 for the reception of pins20 the pu ose of which will be hereinafterdescribed. ominunicatlng with the aperture 15 in each disk is a radially extending slot -or notch 21 adapted to permit 'the' assage of the keys 12 when all of the tumblers have their slots 21 alined.

The tumblers are all exposed through openings 22 in the escutcheon .plates 23 secured to opposite sides of the door and ournaled in `these plates is a rock sha t 24 having manipulating knobs 25-and an intermediate bifurcated lever 26 secured to its center portion. This lever enters a longitudinal Vslot 28 inthe bolt 5 and has its legs straddling a transverse pin ,29 extending across ithe slot' and having one of its ends or terminals arranged in a guiding slot 30 formed in one of the side iplates 31 secured to the door beneath the escutcheon plate 23. This pin engaging the end Walls of the slot 30 limits vtheimovement of the bolt 5 as will .be readily understoodand at the saine time prevents the same from turning in the door.

Slidably mounted in the casing 7 and in `the channel-32 formed in the door is atumbler locking bolt 33 having a, groove 34 arranged in its underside to receive the rojections 17 on the tumblers. This tum ler locking boltis operated by a transverse pin or rod 35 which passes through the bolt 33 and through slots 36 formed in the escutcheon plates, the outer ends of the pin or rod being provided with knobs 37 by vwhich the ections 17 separated by recesses same is manipulated. This tumbler lock is .110

utilized so that if the disks are set with their slots 21 positioned to receive the lassage of the keys the same may be move to engage the projection on lthe set disk so as to prevent its rotation while the other disks are located to aline their slots with the slots of the previously set disks.

The sockets 19 may be normally filled by short screws which come out vflushwith the base of the recesses 18, which screws may be removed so that the pins 2O may be threaded or otherwise secured therein so that the combinat-ion may be conveniently changed. These pins locate the positions of the slots 21 as will be readily understood from the following: In Fig. 8 we will assume that the first recess 18 to the right of the topmost projection 17 is` considered number 1 recess, therefore it will be seen that the pin in this figure is positioned in number 4 recess.. Any suitable arrangement of alining the pins 20 across the openings 22 may be observed; in fact they mayl be arranged dil agonally, straight across t e opening 22 or in V-form across the opening or in any other -suitable'manner, it being understood that when all of the disks have their pins alined or arranged in the referred form across the opening that the sots 21 will all be alined to permit the passage of the keys 12 and by manipulating the knobs 25 the bolt maybe j projected or retracted as desired. In setting up the combination from one side of the door, for instance, as viewed on the drawings, the left disk will be set first and the tumbler lock moved into engagement with the `topmost projection 17, the next disk to the right will then be set and the tumbler lock moved into engagement with its topmost projection, thls order being carried out until all of the disks have been set. In setting the tumblers from'the opposite side of the-door, it will be noticed that the right hand disk' will be the initial disk set.

' combination shown set up in Fig. 7- is '4-1-3--2-75-6, 'and in this instance it will be noted that the order in which the pins are arranged is b the position of the recesses 18, the first disk having its pin in the .fourth disk having its .pin in the second position as shown at d, the fifth disk having its pin arranged in the fth position as The I mounted in the casing, locking tumblers journaled on the bolt and exposed through opposite sides of the casing, coac ing means on the tumblers and bolt for locking the bolt, andrneans slidably mounted in the casing for locking the tumblers in set or unset position.

2. In a lock, a casing, a bolt slidably mounted in the casing and having a series of spaced and alined keys, tumblers rotating upon the bolt and having a notched web adapted to move between th'e keys, said tumblers exposed through the casing on opposite sides thereof and means for locking the tumblers in set or unset position against rotation in either direction.

3. In a lock, a casing, a bolt slidably mounted in the casing and having a series of spaced and alined keys, tumblers rotating upon the bolt and having a notched web adapted to move between the keys, said tumblers exposed through the casing on opposite sides thereof, projections on said tumblers and a locking member carried by the casing jand adapted tolengage said projections to lock the tumblers in set or'unset position aga-inst rotation in either direction.

4. In a lock, a casing, a bolt slidably mounted therein, tumblers journaled upon the bolt and having notches therein a series of alined and spacedkeys on the bolt adapted to pass throughthe notches ofthe -tumblers when all are alined, projections on the periphery of thertumblers, means slidably mounted in the casing for engaging the projections to lock the. tumblers against rota'- tion, said tumblers being exposed through the opposite sides of the casing and locatin pins removably mounted in the tumblers an exposed through opposite sides of the casingl whereby the combination may be change without disconnecting the lock parts to' gether With means for operating the bolt.

In testimony whereof I aflix my signa-` ture in presence of two witnesses.
